Hello all, I've been wanting to upgrade my GPU in my PC for sometime, as a couple months ago I upgraded my mobo, cpu and RAM to something much more modern, and I figure it's time for my graphics card to take the same leap. I've used many of the PSU calculators I can find online, but I still am not sure if I should buy a new power supply before buying my card. I'd rather not have to if it could handle it, but I figured I should ask you fine, knowledgeable people of this forum for a more accurate answer. My relevant PC specs will be listed as below, let me know if I need to provide other information:

PC Specs (Everything will be running stock, no OC)
CPU: Intel i5 4670K (Haswell)
RAM: 8gb G.Skill Sniper RAM (2x4)
MOBO: MSI Z87M Gaming
PSU: 530W Rosewill Green Series
Current GPU: Radeon HD 6770
Planned GPU: MSI Gaming GTX 780

I just want to know if with the new MSI Gaming GTX 780 GPU I'm planning on getting, can my current power supply handle it just fine? I will be overclocking nothing (Except for the stock OC the card comes with), if I decide to do so it will be in the future and only after I've definitely upgraded my PSU, I just want to know if it could run the above planned setup stock, or if I'd be better off just getting a brand new PSU. Thank you very much for your time :)

EDIT: Also, if I am going to have to get a new PSU, I was looking at the Fractal Design Integra R2 750W, good choice or bad choice?

for gtx780 42A is recommended for the 12v rail and your rosewill can output 41A. i would say it deserves a try but make sure you wont o/c cpu or gpu for any reason! since you have money to spend though prefer an upgrade. for the same money fractal design costs you can get this excellent unit and overclock the hell out of it!!!!

Power Supply: EVGA 750W 80+ Gold Certified Fully-Modular ATX Power Supply ($89.99 @ NCIX US)
Total: $89.99
Prices include shipping, taxes, and discounts when available

Hi - As Chris said you might get by with your Rosewill, but if you can afford to upgrade your PSU, you should do
so. It is safe to assume that if you got an Intel 4670K, you intend to OC.

Also, neither your Rosewill or the Fractal PSU's are Haswell ready. While not likely to cause damage to
your system, they could be annoying when the PC tries to awaken from sleep state.

The EVGA recommended above is *Haswell ready if it fits your budget. If it is too much $$, plx post your budget
and I'll look for another. There are other options since you don't need a 750w unit.

*Realhardtechx does not list it as Haswell ready, mfg's feature lists it as Haswell ready.

The most I can foot as a budget for the computer upgrades, as I am starting to be convinced that I could use a good power supply (and why not get the most out of my rig anyway?), is about $700-$750. The current upgrades I'm looking at are:

New Case (Current one can't fit the GTX 780) : NZXT Phantom 410
GPU: MSI Gaming GTX 780
Power Supply: EVGA G2 Supernova 750W

Grand Total: $719.97. Bit on the high end, but I'd rather pay for quality than risk anything, and I figure a new, very highly rated power supply will do me good. These upgrades look solid?
 


http://www.tomshardware.com/news/EVGA-PSU-Haswell-C6-C7,23171.html well this doesnt include 750w/850w supernova g2 models as there are newer but of the same Leadex Super Flower platform so i guess is it is safe to assume they are (haswell compatible) and we are just waiting for the confirmation and yes a quality 650w will be plenty even for o/c!
